Best practices to optimize utilization of the National Living Donor Assistance Center for the financial assistance of living organ donors.

Living organ donors face direct costs when donating an organ, including transportation, lodging, meals, and lost wages. For those most in need, the National Living Donor Assistance Center (NLDAC) provides reimbursement to defray travel and subsistence costs associated with living donor evaluation, surgery, and follow-up. While this program currently supports 9% of all US living donors, there is tremendous variability in its utilization across US transplant centers, which may limit patient access to living donor transplantation. Based on feedback from the transplant community, NLDAC convened a Best Practices Workshop on August 2, 2018, in Arlington, VA, to identify strategies to optimize transplant program utilization of this valuable resource. Attendees included team members from transplant centers that are high NLDAC users; the NLDAC program team; and Advisory Group members. After a robust review of NLDAC data and engagement in group discussions, the workgroup identified concrete best practices for administrative and transplant center leadership involvement; for individuals filing NLDAC applications at transplant centers; and to improve patient education about potential financial barriers to living organ donation. Multiple opportunities were identified for intervention to increase transplant programs' NLDAC utilization and reduce financial burdens inhibiting expansion of living donor transplantation in the United States.

Presence and hazards of nutrients and emerging organic micropollutants from sewage lagoon discharges into Dead Horse Creek, Manitoba, Canada.

Nutrient enrichment and loadings of pharmaceuticals and agrochemicals into freshwater systems are common concerns, especially for water bodies receiving wastewater inputs. In the rural communities of Morden and Winkler of Manitoba, Canada, sewage lagoons discharge their wastewater directly into Dead Horse Creek, a small tributary of the Red River that empties into Lake Winnipeg. This lagoon approach to managing rural wastewaters is common across the North American Prairies. Therefore, this study aimed to assess the hazards of lagoon treatment releases at this model site. This was done by characterizing the nutrients, organic micropollutants (i.e., pesticides, pharmaceuticals) and standard water quality parameters in the creek prior to and following lagoon discharge events over a number of years (2009-2011). Measured concentrations of nutrients were compared to regulatory expectations and micropollutants were assessed using hazard quotients. As expected, concentrations of nitrogen and phosphorus species were greatest in sites downstream of the sewage outfall immediately following discharge events. Pharmaceutical and agricultural chemicals were detected at concentrations between 0.5 and 90 ng/L. Detection frequencies and concentrations matched typical use patterns. Those compounds used predominately for human medicine were detected at downstream sites following discharge events, while those used in an agricultural setting were detected at relatively consistent levels over time at sites both upstream and downstream of the outfall location. Hazard quotients calculated for micropollutants of interest indicated minimal toxicological risk to aquatic biota in the creek, with only erythromycin and diazinon presenting a potential concern to aquatic algae and invertebrates. Concentrations of nutrients exceeded Canadian guideline thresholds during release, but returned to background levels once discharges ceased. Therefore, it is advisable that wastewater treatment and management strategies such as constructed wetlands and/or staggered releases be used in order to minimize the hazard posed by nutrient pulses in Dead Horse Creek and other similar systems.

Predicting the discharge status after liver transplantation at a single center: a new approach for a new era.

The aim of this study was to develop a tool for preoperatively predicting the need of a patient to attend an extended care facility after orthotopic liver transplantation (OLT). A multidisciplinary group, which included 2 transplant surgeons, 2 transplant nurses, 1 nurse manager, 2 physical therapists, 1 case manager, 1 home health care professional, 1 rehabilitation physician, and 1 statistician, met to identify preoperative factors relevant to discharge planning. The parameters that were examined as potential predictors of the discharge status were as follows: age, sex, language, Karnofsky score, OLT alone (versus a combined procedure), creatinine, bilirubin, international normalized ratio (INR), albumin, body mass index (BMI), Child-Turcotte-Pugh score, chemical Model for End-Stage Liver Disease score, renal dialysis, location before transplantation, comorbidities (encephalopathy, ascites, hydrothorax, and hepatopulmonary syndrome), diabetes mellitus (DM), cardiac ejection fraction and right ventricular systolic pressure, sex and availability of the primary caregiver, donor risk index, and donor characteristics. Between January 2004 and April 2010, 730 of 777 patients (94%) underwent only liver transplantation, and 47 patients (6%) underwent combined procedures. Five hundred nineteen patients (67%) were discharged home, 215 (28%) were discharged to a facility, and 43 (6%) died early after OLT. A multivariate logistic regression analysis identified the following parameters as significantly influencing the discharge status: a low Karnofsky score, an older age, female sex, an INR of 2.0, a creatinine level of 2.0 mg/dL, DM, a high bilirubin level, a low albumin level, a low or high BMI, and renal dialysis before OLT. The nomogram was prospectively validated with a population of 126 OLT recipients with a concordance index of 0.813. In conclusion, a new approach to improving the efficiency of hospital care is essential. We believe that this tool will aid in reducing lengths of stay and improving the experience of patients by facilitating early discharge planning.

Contemporary outcomes of outpatients referred for cardiac transplantation evaluation to a tertiary heart failure center: impact of surgical alternatives.

BACKGROUND: The growing epidemic of congestive heart failure in the setting of limited donor-organ availability has mandated continued development and increased utilization of medical and surgical alternatives to cardiac transplantation. We sought to assess current disposition and outcomes of patients recently referred for transplant evaluation to a single high-throughput tertiary referral center. METHODS AND RESULTS: We performed a retrospective observational review of consecutive patients with advanced heart failure who were assessed initially in an outpatient setting by a heart failure cardiologist, with a view to transplant or nontransplant surgical alternatives between 1995 and 2000. Of 1174 consecutive referrals (mean age 55.1 [+/-12.7], 74% male), 588 (50%) were recommended for medical treatment (mean age 55.3 [+/-12.4], 72% male) and 200 (17%) for nontransplant surgery, principally coronary artery bypass grafting, mitral valve repair, infarct exclusion, partial left ventriculectomy, or combinations thereof (mean age 57.8 [+/-10.6], 76% male). A minority, 418 (36%), were initially listed for cardiac transplantation (mean age 53.5 [+/-13.9], 80% male). Of these, 74 (18% of listed) died waiting (34 on left ventricular assist device support), 45 were delisted (27 for improved clinical status), and 217 (18% of referred group) have been transplanted. The 3-year survival (Kaplan-Meier) was equivalent (82%) in the transplanted and nontransplant surgery groups (excluding partial left ventriculectomy patients). CONCLUSION: In current clinical practice less than one fifth of transplant referrals are ultimately transplanted, reflecting both a limited donor supply and the application of alternative, nontransplant strategies. Medium-term survival in patients suitable for alternative surgical strategies equals that of cardiac transplantation.
